What is tolmetin, and how does it work (mechanism of action)?
Tolmetin is a nonsteroidal anti-inflammatory drug (NSAID) that is effective in treating fever, pain, and inflammation in the body. It is similar to ibuprofen (Motrin or Advil), naproxen (Naprosyn), and others. As a group, NSAIDs are non-narcotic relievers of mild to moderate pain of many causes, including injury, menstrual cramps, arthritis, and other musculoskeletal conditions. They work by reducing the levels of prostaglandins, chemicals that are responsible for pain, fever, and inflammation. Tolmetin blocks the enzyme that makes prostaglandins (cyclooxygenase), resulting in lower concentrations of prostaglandins. As a consequence, inflammation, pain and fever are reduced. The FDA approved Tolectin in March 1976.
Is tolmetin available as a generic drug?
GENERIC AVAILABLE: Yes
Do I need a prescription for tolmetin?
Yes
What are the uses for tolmetin?
What are the side effects of tolmetin?
Most patients benefit from tolmetin and other NSAIDs with few side effects. However, serious side effects can occur, and generally tend to be dose related. Therefore, it is advisable to use the lowest effective dose to minimize side effects. The most common side effects of tolmetin involve the gastrointestinal system, and these include:
- ulcerations,
- abdominal pain,
- cramping,
- nausea,
- gastritis,
- serious gastrointestinal bleeding,
- liver toxicity,
- stomach ulceration
- black tarry stools, and
- weakness.
Tolmetin should be avoided by patients with a history of asthma, hives, or other allergic reactions to aspirin or other NSAIDs. Rare but severe allergic reactions have been reported in such individuals. It also should be avoided by patients with peptic ulcer disease or poor kidney function, since this medication can aggravate both conditions.
Other important side effects include:
- heart attacks
- strokes
- accumulation of fluid, and
- increased chance ofheart failure.
Tolmetin may cause or worsen high blood pressure and kidney failure.
What is the dosage for tolmetin?
The recommended dose is 200-600 mg three times daily. The maximum daily dose is 1800 mg. Tolmetin should be taken with food and 8-12 ounces of water to avoid stomach upset.

QUESTION
What joints are most often affected by osteoarthritis? See AnswerWhich drugs or supplements interact with tolmetin?
Tolmetin is generally used with caution in patients taking blood thinning medications (anticoagulants), such as warfarin (Coumadin), because of an increased risk of bleeding. Patients taking lithium (Eskalith, Lithobid) or methotrexate (Rheumatrex, Trexall) can develop toxic blood levels of either drug because tolmetin may inhibit their elimination from the body by the kidney. Side effects from cyclosporine also may be increased by tolmetin. Tolmetin may reduce the effectiveness of antihypertensives because it causes or worsens high blood pressure. NSAIDs may diminish the antihypertensive effect of ACE inhibitors.
Combining NSAIDs with angiotensin receptor blockers (for example, valsartan [Diovan], losartan [Cozaar], irbesartan [Avapro]) or angiotensin converting enzyme inhibitors (for example, enalapril [Vasotec], captopril [Capoten]) in patients who are elderly, volume-depleted (including those on diuretic therapy), or with poor kidney function may result in reduced kidney function, including kidney failure. These effects usually are reversible.
Persons who have more than three alcoholic beverages per day are at increased risk of developing stomach ulcers when taking tolmetin or other NSAIDs.
Is tolmetin safe to take if I'm pregnant or breastfeeding?
Tolmetin is generally avoided during pregnancy.
Tolmetin is excreted in breast milk. To avoid adverse effects in the infant, nursing mothers should decide whether to stop nursing or stop tolmetin.
What else should I know about tolmetin?
What preparations of tolmetin are available?
Tablets or capsules: 200, 400, and 600 mg
How should I keep tolmetin stored?
Tolmetin should be stored at room temperature in a sealed container and protected from moisture.

Osteoarthritis (OA)
Osteoarthritis is a type of arthritis caused by inflammation, breakdown, and eventual loss of cartilage in the joints. Also known as degenerative arthritis, osteoarthritis can be caused by aging, heredity, and injury from trauma or disease.
-
Arthritis (Joint Inflammation)
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, and pseudogout.

Pain Management
Pain management and treatment can be simple or complex, according to its cause. There are two basic types of pain, nociceptive pain and neuropathic pain. Some causes of neuropathic pain include: complex regional pain syndrome, interstitial cystitis, and irritable bowel syndrome. There are a variety of methods to treat chronic pain, which are dependant on the type of pain experienced.

Nonsteroidal Anti-inflammatory Drugs and Ulcers
Nonsteroidal anti-inflammatory drugs (NSAIDs) are prescribed medications for the treatment of inflammatory conditions. Examples of NSAIDs include aspirin, ibuprofen, naproxen, and more. One common side effect of NSAIDs is peptic ulcer (ulcers of the esophagus, stomach, or duodenum). Side effects, drug interactions, warnings and precautions, and patient safety information should be reviewed prior to taking NSAIDs.
-
Reactive Arthritis
Reactive arthritis is a chronic, systemic rheumatic disease characterized by three conditions, including conjunctivitis, joint inflammation, and genital, urinary, or gastrointestinal system inflammation. Inflammation leads to pain, swelling, warmth, redness, and stiffness of the affected joints. Non-joint areas may experience irritation and pain. Treatment for reactive arthritis depends on which area of the body is affected. Joint inflammation is treated with anti-inflammatory medications.
-
SAPHO Syndrome
SAPHO syndrome is a chronic disorder that involves the skin, bone, and joints. SAPHO syndrome is an eponym for the combination of synovitis, acne, pustulosis, hyperostosis, and osteitis. SAPHO syndrome is related to arthritic conditions such as ankylosing spondylitis and reactive arthritis. Treatment is directed toward the individual symptoms that are present, and includes medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), and cortisone medications.
-
Juvenile Rheumatoid Arthritis (JRA)
Juvenile rheumatoid arthritis (JRA) annually affects one child in every thousand. There are six types of JRA. Treatment of juvenile arthritis depends upon the type the child has and should focus on treating the symptoms that manifest.
